7 To all whom it may concern:

Be it known that I, LESTER A. WERNERY, a citizen of the United States,residing in Brooklyn borough, in the county of Kings, city and State ofNew York, have invented certain new and useful Improvements inType-Writing Machines, of which the following is a specification.

This invention relates 'to appliances for typewriting machines, and, inthe form herein specifically disclosed, is particularly adapted foradvancing over the platen a-work sheet or web, consisting of a series ofworkforms adapted to be written upon seriatz'm. The work sheet or devicemay consist of a number of blank forms connected in a continuous web orlong sheet to be advanced over the platen to bring the blank formssedatim into position to'be written upon. A feature of the invention isthe provision of improved means for quickly and accurately advancingeach form into position to be. written upon, when the entries on thepreceding-form have been completed. In the preferred embodiment of theinvention, a handle or driver is provided having a limited throw andmeans cooperating therewith, for advancing the work member to bring anew form into position to receive the first line of writing whenever thedriver is actuated to the limit of its forward movement, regardless ofthe extent the platen has been rotated while entries were being madeupon the preceding work-form.

The driver may be a crank loosely mount-- ed on the platen axle and itsmovement in both directions limited by stops, one'or both of which maybe adjustable to limit the throw of the driver. The driving connectionbetween the driver and the platen may be eflected by means of a couplingdevice, which, in the form disclosed, comprises a dog on the driveradapted to engage the' teeth of a ratchet wheel'which rotates with theplaten. A coupling controller or gage which may be in the form of a diskloose on the platen axle but which may be caused to rotate therewith byfrictional engagement, or other appropriate means, lies in the path ofthe dog and thereby holds the latter out ofengagement with the ratchetwheel dur' ing the rotation of the platen independently of the operationof the driver, said disk Specification of Letters Patent.

Application flied March 27, 1914. Serial No. 827,589.

-turnin with the platen during such rotation. 0 advance thecompleted'work-form into position to be removed and .to bring asucceeding work-form into position to be printed upon the driver isswung forward, and during its initial movement, the dog thereon ridesidly on said disk, until a notch in the disk permits the dog to springinto engagement with the ratchet wheel so that during the final movementof the driver the platen is rotated therewith. The position of the notchat the time the driver is swung forward to engage the ratchet wheeldepends on the distance the platen has been rotated during the writingupon the work-form.

The extent the 'platen is rotated by the the total movement of theplaten being determined by the .total throw of the driver, which isadjusted to' the length of the individual work-form. The driver may bereturned to initial position by a spring, and a lug on said disk, infront of which the dog drops as it enters into said notch, forms adriving connection between the driver and the disk for returning thelatter with the driver. As the driver completes'its return movement, thedog may be lifted by a cam to disengage said lug, thereby releasing thedisk readyfor a subsequent operation.

Other features and advantages will hereinafter appear; and the inventionmay be used for other purposes. v

In the accompanying drawings,

Figure 1 is a front perspective view showing the platen frame and platenof an Underwood typewriting machine with the present invention attachedthereto.

Fig. 2 is a sectional end elevation showing the parts in the positionassumed when- Fig. 5 is detail View of the driving dog.

Fig. '7- is a disassembled view showing successively the ratchet wheel,the friction member, the interponent disk between which and the ratchetwheel .said friction member is arranged, and a hand wheel.

A rotary platen.1 is fixed to an axle 2 journaled in the ends 3, 4 ofthe platen frame, said ends connected by an inclined paper shelf 5 atthe rear of the platen. The platen may be rotated either by hand wheels6 on the ends of the platen axle, or by the upon, the platen may befurther rotated to bring the next'form into position by means of adriver 13 which as herein shown, comprises an arm extending radiallyfrom a disk 14 loosely mounted on the platen axle 2, said arm providedat its outer end with a handle 15. A coupling device to establish adriving connection between the driver and the platen is provided, andcomprises, in the form disclosed, a ratchet wheel 16 and a dog 18. Theratchet wheel 16 is fixed to the platen axle as by means of a pinextended through the hub 17 of said wheel and through the said axle. Adog 18 slidably mounted on the driver 13 is formed with a beveled tooth19 to engage the ratchet wheel 16 to drive it in a forward direction,

, but permits forward rotation of the platen independently of thedriver. The dog 18 comprises a neck 20, extending through an elongatedslot 21 in thedriver, and a plate 22 having a slot-and-pin connection23, 24, with the driver. A stem 25 on the plate 22 is guided in a lug 26on the driver 13, and a spring 27 surrounding said stem between the lug26 and the plate 22 moves the dog 18 radially inward to engage theratchet wheel 16.

An interponent between the dog and ratchet wheel 16 for holding the dogoff the ratchet wheel is shown in the form of a disk 28 having a hub 29loosely mounted on the hub 17 of the ratchet wheel, and said disk issubstantially of the same diameter as that of the ratchet wheel, so thatthe periphery of the disk engages the tooth 19 of the dog 18 and holdsthe latter out of driving engagement with the .ratchet wheel, exceptwhen said tooth is brought into position to enter a notch 30 in the diskand thus connect the driver with the ratchet wheel. The disk 28 thusconstitutes a gage or coumeat 4e pling controlling device for determininthe point at which the couplingdevice sh 1 become efi'ective during theadvance'movement of the driver. The hub 29 on said disk is frictionallyheld against the hub of the adjacent hand wheel 6 by. means of a sprmg,shown as a c'onvexed sheet metal ring or disk 31 of resilient material,interthe disk 28 and the ratchet and extending outwa dly from a disk 36loosely mounted on the platen axle between the driver disk 14 and theratchet wheel 16. Within the tube 33 is a holding pin or bolt 37 adaptedto enter any one of an annular series of openings 38, in the disk 34,thereby holding the stop 33 in any desired position relative to the stop32. The openmgs 38 may be spaced at line-space intervals. The bolt 37may be withdrawn by a knob 39 against the tension of a spring 40; v

housed in the tube 33 and bearing against a collar on the bolt 37. p

The driver 13 is normally held against the stop 32 by means of areturning spring 41 shown as a coil spring, housed within the spaceprovided by recessing the opposing faces of. the disks 34, 14, one endof said spring secured to the disk 34 and the other end secured to thedisk 14. Whenever the driver 13 is returned to starting position (Fig.2) the disk 28 is carried with it, being connected to the driver by alug or detent 42 on the outer face of the disk in the path of anoverhanging lip 43 projecting beyond the tooth 19.

The operation may be summarized as follows:

The worksheet or web comprising, for example, a series of printed formsor blanks is placed on the machine and the first form positioned toreceive the first typewritten entry. The driver 13 and interponent disk28 being at the starting position shown in Fi 2, the desired entries arenow typewrltten upon the work-form, during WhlCll operation the platenis rotated by the linespace lever or the hand wheels 6, a greater orless extent depending upon the required entries on the work-form. Duringsuch rotation of the platen, the driver 13 remains at rest, the tooth 19being held free from the ratchet wheel 16 by a cam surface 44 on thedisk 34, which surface, as the driver was returned to starting position(Fig. 2) engaged a shoulder 45 on the locking dog and lifted the latterfree from the ratchet wheel moved, if desired.

It will be noted that as the platen is rotated prior to the operation ofthe driver the disk 28 is carried with it and rotated a variabledistance determined by the position to which the work-form has beenbrought by the time the typewrittenentries thereon have been completed.The entire distance however, through which the platen is rotated,determined-by the throw of the driver, 13, is constant. In \other words,the distance the platen is rotated by the driver is complemental to thedistance it'is rotated prior to the operation of the driver and the sumof these distances is measured by the distance between the stops 32 and33. These stops may therefore be set for work-forms of any length withinthe range ofothe mechanism, so that each time the driver is actuated, anew form. is fed into position for receiving the first line of writing.When the tooth 19 enters the notch 30 during the forward movement of thedriver, the lip 43 moves inward in front of the lug 42, so that when thehandle 15 is released and the driver returned by the spring 41, the disk28 is carried with it until the shoulder 45 rides on to the cam face 44as the driver completes its return movement. Thus the disk 28 is alwaysreturned to the same starting position. During the return of the driver,the tooth. 19 rides idly over the ratchet wheel, so that the platenremains at rest. The teeth on the ratchet wheel do not throw the dog outa suificient distance during such return movement to free it from thelug42.
